What ClassiCube is
- Works with both
minecraft.net(classic has been removed by Mojang) and classicube.net accounts.
- Lightweight, minimal memory usage compared to the standard client.
- Works with effectively all graphics cards that support OpenGL or Direct3D 9.
- Provides single-player support, and both a flatgrass and vanilla-type map generator.
It does not work with 'modern/premium' Minecraft servers.
- Windows: XP or later.
- OSX: Only tested on OSX 10.5, may or may not work on later versions.
- Linux: libcurl and libopenal.
Initially, you will need to run ClassiCube.exe to download the required assets from minecraft.net. Just click 'OK' to the dialog menu that appears when you start the launcher.
Singleplayer Run ClassiCube.exe, then click Singleplayer at the main menu.
Run ClassiCube.exe. You can connect to LAN/locally hosted servers,
minecraft.net servers, and classicube.net servers through the launcher.
If you are stuck using the built-in OpenGL 1.1 software renderer, you can use the MESA software renderer from either here or here for slightly better performance. Typically though, this occurs because you have not installed GPU drivers.
*You will likely need to do
chmod +x ClassiCube before running the game.
Press escape (after joining a world) or pause to switch to the pause menu.
Pause menu -> Options -> Controls lists all of the key combinations used by the client.
Note that toggling 'vsync' to on will minimise CPU usage, while off will maximimise chunk loading speed.
Press F to cycle view distance. A smaller number of visible chunks can improve performance.
If the server has disabled hacks, key combinations such as fly and speed will not do anything.

Compiling with Visual Studio:
Open ClassiCube.sln and compile it.
Compiling with MinGW-w64
I am assuming you used the installer from https://sourceforge.net/projects/mingw-w64/
- Install MinGW-W64
- Use either Run Terminal from Start Menu or run mingw-w64.bat in the installation folder
- Compile with the same flags as under Cross Compiling for windows, but use gcc instead of i586-mingw32msvc-gcc
Compiling with MinGW
I am assuming you used the installer from http://www.mingw.org/
- Install MinGW. You need mingw32-base-bin and msys-base-bin packages.
- Run msys.bat in the C:\MinGW\msys\1.0 folder.
- Compile with the same flags as MinGW-w64, but also add
Install appropriate libs as required. For ubuntu these are: libx11-dev, libgl1-mesa-dev, libopenal-dev, libcurl4-gnutls-dev or libcurl4-openssl-dev
gcc *.c -o ClassiCube -lm -lpthread -lX11 -lGL -lcurl -lopenal -ldl
Cross compiling for windows:
i586-mingw32msvc-gcc *.c -o ClassiCube.exe -mwindows -lws2_32 -lwininet -lwinmm -limagehlp -lcrypt32 -ld3d9
gcc *.c -o ClassiCube -framework Carbon -framework AGL -framework OpenAL -framework OpenGL -lcurl
gcc *.c -o ClassiCube -I /usr/local/include -L /usr/local/lib -lm -lpthread -lX11 -lGL -lcurl -lopenal -lexecinfo
Install libexecinfo package if needed.
gcc *.c -o ClassiCube -I /usr/X11R6/include -I /usr/local/include -L /usr/X11R6/lib -L /usr/local/lib -lX11 -lGL -lcurl -lopenal -lexecinfo

NOTE: You have to change entry->d_type == DT_DIR to Directory_Exists(&path) (TODO do this automatically)
emcc *.c -s FETCH=1 -s ALLOW_MEMORY_GROWTH=1 --preload-file texpacks/default.zip
You'll have to write the necessary code. You should read portability.md in misc folder.
Functions and variables in .h files are mostly documented.
Further information (e.g. portablity, style) for the game's source code can be found in the misc folder.
